Answer:
option D is correct
D. This solution is a good buffer.
Explanation:
TRIS (HOCH
)
CNH
if TRIS is react with HCL it will form salt
(HOCH)CNH + HCL ⇆ (HOCH)NHCL
Let the reference volume is 100
Mole of TRIS is = 100 × 0.2 = 20
Mole of HCL is = 100 × 0.1 = 10
In the reaction all of the HCL will Consumed,10 moles of the salt will form
and 10 mole of TRIS will left
hence , Final product will be salt +TRIS(9 base)
H = Pk
+ log (base/ acid)
8.3 + log(10/10)
8.3

Gummy bears are made in a special factory with many different tools in it that process the gummy bears
The low pressure system wind flow in a counterclockwise direction toward the center because low pressure are connected, and in fact often generally, by upper atmosphere with winds. Winds generally blow from high pressure to low pressure areas at the surface. The direction of deflection is caused by the rotation of the Earth and the resulting Coriolis effect.
A way to remember this is.....some stoners like to get "high around the clock" (as in clockwise, but please don't do this!!)
Low pressure systems usually bring cloudy stormy conditions, while high pressure system bring clear bright skies and in the summer, warm weather.
Protons, neutrons, and electrons are the fundamental subatomic particles.
